Illustrate any ‘three’ genes which can be used in gene therapy. - Biology

Short Note

Illustrate any ‘three’ genes which can be used in gene therapy.

Enlist the genes used in gene therapy.



Some examples of genes that can be used in gene therapy:

  1. Tissue growth factor-beta (TGF-β): It promotes new blood vessels and epidermal growth. It is useful in wound healing and the treatment of burns.
  2. Tissue plasminogen activator (TPA): It is used to prevent or reverse blood clots.
  3. Human blood clotting factor VIII: It is used to aid in the clotting of blood and to treat patients suffering from haemophilia.
